F is a bit confusing. Why wouldn't PRODUCT_NAME be able to have duplicates? Isn't that a common requirement for product databases?

Leana: That's a good point. In that case, we might need to use a different unique identifier for each product.

But what if there are products with the same name but different attributes?

F is correct because PRODUCT_NAME is usually a unique identifier for products.

D is interesting. Does EXPIRY_DATE really contain SYSDATE by default? That could be a tricky gotcha if you're not expecting it.

I disagree with both of you. I believe D is true because SYSDATE is automatically assigned to EXPIRY_DATE if no date is specified.

I agree with you, Catarina. I also think C is true because dates cannot be used in arithmetic expressions.

Wait, is EXPIRY_DATE the field for when the product expires, or when the exam expires? I always get those mixed up.

B and E look good to me. PRODUCT_ID should definitely be the primary key, and PRODUCT_PRICE having a default of 0 makes sense.
